body of mass 2kg is moving according to displacement s=t^3i+t^2j then find out power at t=2 sec also find out average power in first 2 sec

What statements accurately describe atoms

F500 j of energy were added to 1 kg of each of these samples, which would experience the least temperature increase?

The pressure increases by 1.0 x 104 n/m^2 for every meter of depth beneath the surface of the ocean. at what depth does the volume of a pyrex (bulk modulus 2.6 x 1010n/m^2) glass cube, 9.8 x 10^−2m on an edge at the ocean's surface, decrease by 7.5 x 10−10m^3? explain the formula beyond this point: p=1.0x10^4, b=2.6x10^10, l=9.8x10^−2, delta v=7.5x10^−10. at some point l needs to be cubed. why p is divided by delta v?
